According to Leonardo Andrea, SC genealogist, in his "Counties in SC" (FHL film 954,248, and from Louis Boone)
Extinct counties after the Revolution included:
Lewisburg County was formed in 1785 but after 1790 was united with Orangeburg County and all records were in Orangeburg. Sherman burned the records in 1865.
Saxe-Gotha County was formed from old Orangeburg in 1785. The name was later changed to Lexington County. The records are at Lexington S.C. Sherman burned the C.H. in 1865. Some books from 1825 on were saved.
